Moore, Walker out of Scotland squad
Scotland have hit by two late withdrawals from their World Cup squad.
Batley half-back Gareth Moore, whose Championship Grand-Final appearance last month was his final one for the Bulldogs ahead of his move to Featherstone, has pulled out with a shoulder injury, while a persistent knee problem as scuppered the hopes of Castleford prop Jonathan Walker lining up alongside his twin brother Adam.
Scotland coach Steve McCormack has potential replacements lined up in Workington scrum-half Callum Phillips and Whitehaven's former Castleford prop Paul Jackson.
Phillips trained with the Bravehearts at Featherstone on Sunday in a pre-planned arrangement to help him gain experience alongside older brother Brett, his club-mate who won his first Scotland cap last year.
Scotland will send medical reports on Moore and Walker in the next 48 hours as they seek permission from RLWC2013 to replace them in the 24-man squad that was named last Wednesday.
Scotland captain Danny Brough, the Huddersfield skipper and recently-crowned Super League Man of Steel, Sheffield Eagles captain Mitchelll Stringer were among the players who linked up with the squad as McCormack stepped up his preparations for Saturday's warm-up match against Papua New Guinea at Featherstone.
McCormack had 19 players in training and they are due to be joined by Catalan Dragons hooker Ian Henderson and NRL trio Peter Wallace, Kane Linnett and Luke Douglas later in the week.
